Well I searched around and really couldn't find a list of tank mates that would work well with a male betta. He is pretty sweet and has never really bothered anyone in previous setups I have had. I have a 10 gallon tank that I am planning to add a couple plants too. My last setup was 5 neon tetras, two cory cats, and the betta. I'd like to have the cories again as I just love them and have this betta. I just recently moved and brought the betta with me. This little guy has traveled close to 1500 miles with me and I'd like to see him have another nice setup to swim around in.
